Abstract
Embodiments include a method of performing math based currency ('MBC') exchanges. One method includes receiving an exchange request from a merchant point-of-sale (POS) system and determining a merchant POS system accepts MBC payments. The method further includes exchanging, on a published blockchain, an amount of MBC equal to an amount to an MBC account of the merchant POS system and updating a pooled account database. The method further includes updating an overlay ledger to modify an MBC balance of the MBC credit card account held by the customer and broadcasting the exchange to a plurality of MBC verification nodes for verification.
